Inspection of Radiation Protection Arrangements and Control of Radiation Exposure

Executive summary

Purpose of intervention

This report describes an inspection of Magnox Ltd's Chapelcross licensed site, undertaken as part of a series of routine interventions set out in the Integrated Intervention Strategy document for 2016/17. The intervention also met the requirements of the planned ONR cross sites intervention for Chapelcross, which is looking at Control of Radiation Exposure (CORE) across all licensee sites.

Interventions Carried Out by ONR

During the intervention a compliance inspection was undertaken on:

The Ionising Radiations Regulations 1999

The intervention was conducted principally under regulation 8 of the Ionising Radiations Regulations 1999 (IRR99). To ensure consistency with previous CORE inspections, the inspection was conducted using a standard questionnaire and follow up face-to-face question and answer session with key representatives at Chapelcross. During the intervention we viewed application of arrangements for controlling radiation exposure by visiting a number of areas including decommissioning areas, the reactor 4 building and pile cap, ponds, waste disposal and storage buildings.

Explanation of Judgement if Safety System Not Judged to be Adequate

This intervention did not include a safety system based inspection.

Key Findings, Inspector's Opinions and Reasons for Judgements Made

Compliance with the requirements of the IRR99 was judged overall to be GREEN. ONR advised on a number of areas for improvement in order to achieve a closer alignment with published relevant good practice.

Conclusion of Intervention

Compliance with the IRR99 was judged to be of an adequate standard with some opportunities for further improvement identified which were discussed at the closing meeting.
